Why choose Sapphire?
One of the hardest materials available

Superior IR & UV transmission compared to other optical materials

Highly scratch & abradant resistant

Highly chemical resistant

Maximum temperature rating of almost 2000℃

Excellent dielectric & loss tangent performance

Sapphire Windows are manufactured from single crystal sapphire, making them ideal for demanding applications (such as laser systems) because of their extreme surface hardness, high thermal conductivity, high dielectric constant and resistance to common chemical acids and alkalis. Sapphire is the second hardest crystal next to diamonds and, because of their structural strength, sapphire windows can be made much thinner than other common dielectric windows with improved transmittance. Chemically, sapphire is single crystal aluminum oxide (Al2O3), and is useful in a transmission range from 0.2 - 5.5µm.
